Dramatic footage shows a heavily-pregnant snake spilling dozens of baby anacondas onto the road after it was run over and squashed.

Fisherman Ederson Negri Antonioli came across the heartbreaking scene on Monday (6 Jan) and filmed it for his followers.

His graphic footage shows the 5m-long (16’5”) boa and its 40-odd offspring scattered on the tarmac.

Antonioli told local media that parts of the long snake were still moving when he first found it.

The water boa was due to give birth at any moment when it was run over on the MT-338 highway in Porto dos Gaúchos, Brazil.

The reptile has been identified as a southern green anaconda (Eunectes murinus).
